The Transportation Safety Institute (TSI), a fee-for service organization that operates without a direct appropriation, supports the U.S. Department of Transportation’s goal to reduce transportation-related deaths and injuries through quality instruction to those entrusted with enforcement and committed to compliance. For 40 years, TSI has provided training to Federal, State, and local governmental, private sector, and foreign transportation professionals on a cost-recovery basis. More than 800,000 students have received TSI’s high-quality safety and security training in aviation, highway traffic, transit, motor carriers, and hazardous materials. TSI is part of DOT’s Office of the Assistant Secretary for Research and Technology (OST-R), whose mission includes coordinating DOT’s research and education programs and advancing technologies throughout our transportation system.
